  • Various drones have extended application area very fast. In this paper, we define two contradictions in designing a portable-size drone by using TRIZ technique. The first is a physical contradiction between high rigidity and good portability, and the second is a technical contradiction between high stability and good portability. Through TRIZ technique, six design principles, which guide direction for optimal design, were driven. Consequently, an umbrella mechanism and design criteria were proposed for a portable-size drone. Detail design is verified through finite element method. Test results for the portable-size prototype drone show good performance, and prove its usefulness to be equivalent to a general full-size drone.

  • A total of 6 tamaraws were observed for determining coat color and measured for body conformation. Banding pattern of 4 blood proteins and 2 isozymes were analysed from the peripheral blood of two tamaraws. The coat colour of younger tamaraws were observed to be brown and adult was found to be complete black. The body weight, body length, withers height, head length, head width, horn length and tail length of adult male and female tamaraws were: 236 kg and 208 kg; 113.5 cm and 112.5 cm; 19.5 cm and 20 cm; 30.0 cm and 28.5 cm and 36.0 cm and 35.5 cm, respectively. The electrophoretic banding pattern, distance migrated and the allelic frequencies obtained in tamaraws were similar compared with that reported in swamp buffaloes. Although the sample size was very small, results of this study could be an important source of informations based on which a breeding programme can be designed to exploit some of the economic characters of tamaraw.

  • CCTV image processing techniques have been developed for safety management in manufacturing sites. However, CCTV growth has become a social problem for video surveillance with regard to privacy. This study aims to manage the safety system efficiently and protect privacy simultaneously. In this study, the CCTV monitoring system is composed of five steps (accident monitoring, detection, notification, management, restoration). De-identified image is observed when we are in a normal situation. De-identified image changes to identified image when it detects an accident. As soon as it detects an accident, the accident information is sent to the safety administrator. Then the administrator could conduct safety measures. Afterward, accumulated accident data could be used for statistical data that could be utilized as analyzing expecting accident.

  • The Halliwick method was developed by Mr. James McMillan, a Canadian engineer of fluid mechanics. In 1949 he started to teach physically handicapped girls to swim at the "Halliwick school for crippled Girls" in London. The Halliwick method has four important basic units, as is shown in Fig 1. This constribution only deals with the structures or the practical part of the method. This part is also known as the 10-point programme. Before the characteristics of the 10 points are dealt with seperately, a few general remarks about these ponits have to be discussed. Of all things happening in the water, fun is the most important one. Swimming is fun! Swimming is taught in an order McMillan describes as: mental Adjustment(M.A), balance restoratiion(B.R.), inhibition(Inh.), and facilitation(Fac.). The 10 points of structure are linked to each other as well as to the learning process as is shown in Fig 3. The Halliwick method, which was devised by James McMillan, has proved to be a very successful way of establishing the basic principles as they have described in this article.

  • How to determine the right number of small base stations to activate in multi-cell uplinks to match traffic from a fixed quantity of K users is an open question. This paper analyses the uplink cooperative that jointly receives base stations activation to explore this question. This paper is different from existing works only consider transmitting power as optimization objective function. The global objective function is formulated as a summation of two terms: transmitting power for data and coordinated overhead for control. Then, the joint base stations activation and beamforming problem is formulated as a mixed integer second order cone optimization. To solve this problem, we develop two polynomial-time distributed methods. Method one is a two-stage solution which activates no more than K small base stations (SBSs). Method two is a heuristic algorithm by dual decomposition to MI-SOCP that activates more SBSs to obtain multiple-antennae diversity gains. Thanks to the parallel computation for each node, our methods are more computationally efficient. The strengths and weaknesses of these two proposed two algorithms are also compared using numerical results.

  • The purpose of this paper is to forecast the future of library education in Korea. Toward this purpose, first, the historical events of library education in the United States of America and in the United Kingdom are introduced along with the IFLA Standards for Library Schools and the Unesco's General Information Programme. Secondly, the theoretical foundations of library education are extracted from the events. Thirdly, the factors influencing library education as well as library developments are identified, and, finally, the prospects of library education are forecasted in the light of the various factors in the Korean society and the theoretical foundations. The prospects are forecasted as follows: 1. The education for information science will be incorporated in library education. 2. The number of courses related to library services and uses will be increased. 3. The students should be provided with enough hands-on experiences to be familiar with new information technology. 4. The cooperation between library schools and libraries will be reinforced. 5. The departments of library science will cooperate with other departments in the universities in order to utilize the expertise and facilities. 6. The education of graduate schools will be specialized to produce subject specialist librarians and the undergraduate education will produce public and school librarians. 7. Opportunities for continuing education will be provided more and librarians encouraged to participate in those activities. 8. Library association should actively be involved in library education as a provider of continuing education or as a liaison between library schools and libraries. 9. The courses of foundations including library history, library research and preservation of culture will never be neglected.

  • Digital library research has attracted much attention. While many research projects are funded by government agencies and national and international bodies, some are run by specific academic and research institutions and libraries. While some digital library projects, such as the ELINOR project in the UK, the first two phases of the eLib(Electronic Libraries) programme in the UK, and the first phase of the DLI(Digital Library Initiative) in the USA, are now over, a number of other projects are currently under-way in different parts of the world. Beginning with the definitions and characteristics of digital libraries proposed by various researchers, this paper provides brief accounts of some major digital library projects that are currently in progress, or are just completed, in different parts of the world. There follows a review of digital library research under 16 major headings. Literature for this review has been identified through a search on the LISA CD-ROM database and a Dialog search on library and information science databases, and the resulting output has been supplemented by a scan of the various issues of D-Lib Magazine and Ariadne, and the Web sites of various organizations and institutions engaged in digital library research. The review indicates that we have learned a lot through digital library research within a short span of time. However, a number of issues are yet to be resolved. The paper ends with an indication of the research issues that need to be addressed and resolved in the near future in order to bring the digital library from the researcher's laboratory to the real life environment.

  • Entrepreneurship development has increasingly become a global solution to address the problem of rising unemployment. Science, Technology and Innovation (STI) have become important tools in improving the economic performance and social well-being of nations. When universities and industry work together to push the boundaries of knowledge, they become a powerful engine for innovation and economic growth. This paper is based on focus group interviews and discussions conducted with key players involved in the HIT-Sandown-UNDP Business Incubation Programme in Harare Zimbabwe. The business incubation project sought to support young Zimbabweans to transform their technical prototypes into commercially and socially viable ventures. As a result, a total of 10 prototypes were refined and investor ready business plans were developed for capital sourcing purposes. It was only through the coming together of the partners that real transformation of the lives of the participants was achieved through learning valuable business skills, coaching and mentoring. University-industry partnerships are a useful vehicle of setting up sustainable business incubation centres.

  • Choi et al's work [1] in 2015 demonstrated that the resident registration numbers (RRNs) of individuals could be conveniently estimated through their personal information that is ordinarily disclosed in social network services. As a follow-up to the study, we introduce the status of the RRN system in Korea in terms of its use in the online environment, particularly focusing on their secure use. We demonstrate that it is still vulnerable against a straightforward attack. We establish that we can determine the RRNs of the current president Moon Jae-In and the world-class singer PSY.
